Iris dark brown ; bill black ; legs black in the male, dark 

 brown in the female. 



The total length, measured in the flesh, varies from 6 5- 

 7 inches. 



The present series contains specimens which are referable 

 to P. picata Gould, as defined by Dr. Hartert [cf. Nov. Zool. 

 xii. p. 220). They occur together with P. bicolor at Crooker- 

 dine Lake, &c. According to Dr. Hartert intermediate 

 examples occur in South-western Australia, and this is 

 certainly the case in the present collection. The chief 

 difference seems to be one of size, typical P. bicolor being 

 distinctly larger.
